Researchers develop polymer-TADF emitters using induced conjugation

Researchers from the Technical University in Dresden have developed a method to produce polymer TADF emitting molecules. Up until now most TADF materials are based on small molecules or chromophores linked to a polymer network.

This research focused on actual polymer TADF, and using a controlled extension of the conjugation of the monomers HOMO wavefunction, the researchers were able to to increase thephotoluminescence quantum yield from about 3% to about 71%. The reseachers say that this is an encouraging first step towards polymer TADF emitters.
